In this article , I'm explaining how to extend your ebs machine volume. Let the EBS volume created is: /dev/sdf and you are creating one volume.
Now take back up of /opt
#mkdir /opt_backup #cp /opt /opt_backup>
- Login to your instance using your terminal.
- type fdisk /dev/sdf
- At "Command" type n
- At "Primary or Extended" type p
- At Number of volumes type 1
- Press "Return" two times to accept the default cylinder values
- Press "w" to write the partition table and exit
- Type "mkfs.ext3 /dev/sdf" to format an ext3 file system
- Type mount /dev/sdf /opt to mount the drive
- edit /etc/fstab to add the drive mount to automount at boot.
add this line:
/dev/sdf /opt ext3 defaults 0 0
- You have successfully attatched a new volume to your running instance.Type “df -h” in terminal to check it
- copy back data from /opt_backup to /opt
#cp /opt_backup /opt
